*1. Using within the set distance enables high-speed responsiveness and a more stable repeat accuracy.*2. The response frequency is an average value.*3. When used at a power of 12 V, the Sensor is less susceptible to the effects of internal self heat generation andtherefore a more stable repeat accuracy can be obtained.*4. When the control output is 20 mA or less, the Sensor is less susceptible to the effects of internal self heatgeneration and therefore a more stable repeat accuracy can be obtained.*5. 3 dia., M4: load current 50 mA, cable length 2 m4 dia., 5.4 dia., M5: load current 100 mA, cable length 2 m6.5 dia.: load current 200 mA, cord length 2 m*6. Oil resistance in-house standard: Performance with respect to water insoluble oil. (Test at right)*7. Material name in EN standards.*8. Clamping nuts: 2 pieces, toothed washer: 1 piece
